Discussion

One of the coldest patterns in many years to start the month of December will result in below-normal temperatures right through this week and we’ll have to monitor a couple of systems that can bring some wintry precipitation to the region. After cold and relatively quiet days today and tomorrow, the mid-week will feature a “clipper” system dropping southeastward from central Canada to the Great Lakes region. This system will pass by to our north on Wednesday night, but it can bring some snow showers to the area and its trailing cold front should push through on Thursday ushering in another cold air mass for the late week and weekend. This frontal system may produce strong wind gusts around here on Thursday as there will be a powerful jet streak associated with it in the upper part of the atmosphere. Another low pressure system may impact us here with wintry precipitation sometime during the latter part of the upcoming weekend.
